In my experiences, No, not for the most part.
There, they are also, those with a mean and hurtful spirit, as they are in any group or crowd. They do not
usually remain a part of any long term congregation. When they sense that
people are getting there " number", they move on, as all bullies do.
Most Church going people, no matter what " Church", come for the healing, then the learning, and finally to encourage others to grow in the faith. Some, well versed and well living people, do not attend the Church house meeting at all, because, they too, have been scarred by such mean spirited people.
The basic belief of the Chruch dictates, that we are to accept you, on faith, as you present yourself, before knowing what you really are. Most of the time, this is a great and noble thing, sometimes, there is a bad seed among us.
